    Youth Climate Action Summit
    8:30 am to 3:00 pm
    Schuylkill Center for Environmental Education, 8480 Hagys Mill Rd, Philadelphia, PA 19128, USA

    Youth Climate Action Summit

    April 4, 2020
    8:30 am to 3:00 pm, 7 hours
    Schuylkill Center for Environmental Education, 8480 Hagys Mill Rd, Philadelphia, PA 19128, USA
    While our world continues to change at an unprecedented rate, legislators have all but halted action on climate change, paving the way for the larger-than-life youth climate activists that have emerged in the last decade. From 16-year-old Time Person of the Year Greta Thunberg who has inspired Fridays for Future movements across the world to Indigenous youth water protectors at Standing Rock to the increasingly influential Sunrise Movement – it has become apparent that those who are speaking the loudest on the frontlines of this fight are those with the most at stake – our youth.

    Our first annual Youth Climate Action Summit for middle and high school aged students and teachers will serve as a platform for young climate activists to come together to discuss key environmental issues, learn from local leaders in the field, and showcase innovative solutions. The day will include a keynote speech followed by engaging break out sessions and talks. Registration is required and check-in begins at 8:30 am.

    Webinar: Combating Climate Change Through Regulatory Relief

    April 13, 2020
    4:00 pm to 5:00 pm, 1 hour

    As the climate change crisis becomes increasingly apparent, there are growing calls from policymakers and academics to reduce regulatory burdens on zero-carbon renewable energy development. But extreme scenarios, such as exempting renewables from most environmental and land use laws, could backfire.

    Transitioning rapidly to renewable energy will be an essential tool to slow the pace of climate change. And easing regulatory requirements for renewables will be a key part of this toolkit. But exempting renewables from land use laws could backfire due to public opposition. Further, new laws will be necessary to ensure that the rapid transition is as “just” as possible—that workers in the fossil fuel industry have the retraining they need and want; that fossil fuel-dependent communities receive funding and guidance for developing innovative, sustainable industries; and that new energy development does not perpetuate existing environmental justice issues.

    Join us for an exploration of a middle ground option, in which we develop renewable energy at a fast clip—while still addressing important social and environmental impacts. The conversation will feature Visiting Scholar Hannah Wiseman and Professor Cary Coglianese.
